[Bug 21411] New: ExitDuringStepTestCase hanging on buildbot and local runs on FreeBSD

Bug ID 21411
Summary ExitDuringStepTestCase hanging on buildbot and local runs on FreeBSD
Product lldb
Version unspecified
Hardware PC
OS FreeBSD
Status NEW
Severity normal
Priority P
Component All Bugs
Assignee lldb-dev@cs.uiuc.edu
Reporter emaste@freebsd.org
Classification Unclassified

Unfortunately the buildbot output is not useful: the test runs ninja check-lldb
but is killed by timeout after 1200s and none of the output is displayed.

Running the suite locally on FreeBSD 10.1-RC3 I see that the test suite is
executing the exit_during_step test and making no progress.

Example output:
